Mavic
Ksyrium Pro UST Disc Centerlock WTS Front

Details

A favorite for everyday road training and racing, this versatile wheel system produces a lightweight, dynamic ride quality that now has the added benefits of Mavic's UST Road Tubeless technology. This patented system provides seamless integration between the wheel and Mavic's new Yksion Pro UST tubeless tires that makes installation, removal and maintenance easier than ever. And you get all the benefits of tubeless, including less rolling resistance and a smoother, more controlled ride quality. Without tubes, you can run lower tire pressure without risking pinch flats, and the sealant helps prevent punctures. The rims are engineered using Mavic's ISM 4D technology and now feature a wider design (19mm internal/23mm external). ISM stands for Inter Spoke Milling, a unique process that trims the thickness of the rim wall between the spokes to create a rim that’s lighter but still very durable. To reinforce the front wheel for disc brakes, Mavic increased the spoke count to 24. The hub is compatible with a 12mm thru-axle, 15mm thru-axle or quick release. The rear wheel uses 24 straight-pull spokes laced to Mavic's lightweight, fast engagement Instant Drive 360 hub mechanism. Delivered in 12x142, it can be also converted to regular quick release. It’s compatible with Shimano or SRAM cassettes and can be converted to Campagnolo or SRAM XD-R.

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.

Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.

UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire bead. UST rims should be paired with UST-specific tires for best results.
